[Diet and precancerous gastric lesions: preliminary results of a sampling study of homogeneous population]. / Dieta e lesioni gastriche precancerose: risultati preliminari di uno studio condotto su un campione di popolazione omogenea.

The aim of this study was to analyse the relationship between dietary factors and precancerous gastric lesions in the population of a commune in the province of Latina which, on the basis of data published by RTP-LT, appears to present a striking incidence of so-called diet-dependent tumours. A series of tests was used to evaluate the antioxidising (protective) and pro-oxidising (encouraging) capacity of the following substances in terms of cancerogenesis: lutein, zeoxanthine, cryptoxanthine, lycopene, alpha and beta carotene, total carotenoids, tocopherol, retinol, ascorbic acid, cholesterol, HDL cholesterol, triglycerides and ceruloplasmin. Two sample populations were enrolled in the study: sample A (random) composed of 400 persons (202 males and 198 females) aged between 20 and 80 who underwent esophagogastroduodenoscopy and multiple biopsies of the gastric mucous; sample B (random), representative of the population, composed of 400 persons (200 males and 200 females) aged between 20 and 80, who underwent plasmatic assay of lipid and vitamin status. The results of this study appear to confirm the hypothesis of a correlation between diet and pre-cancerous lesions and suggest that the primary preventive stps take the form of: a) reduced intake of animal fat; b) increased consumption of fresh vegetables.

Personality patterns of headache sufferers.

One hundred and sixty-seven subjects (91 females and 76 males) aged 18 to 55 and suffering from recurrent headache, daily headache, and cluster headache, were studied. In order to collect detailed information about their clinical as well as social and environmental conditions, a multi-page card was used which had been specially prepared for this purpose. The patients' personality patterns were assessed by the following methods: MMPI (the Hs, Hy, D, and Ma scales, in particular); EPQ (Eysenck Personality Questionnaire); and AS IPAT (Cattel's Anxiety Scale). The statistical analysis of the data obtained made it possible to define the personality patterns of both male and female subjects and then to differentiate between them in relation to the various types of headache. Furthermore, possible relationships between personality traits and headache suffering were investigated. If the personality patterns of females seem to have existed prior to the disease, those of males raise some questions. In cluster patients, in particular, the age of onset seems to be related to certain personality traits; in patients with daily headache, by contrast the association between the duration and severity of the disorder appears to play a major trigger role. Some of these correlations do not have a linear character and suggest new working hypotheses that go beyond the limits of standard correlations.
